RICHMOND, Va., June 21, 2013

RICHMOND, Va., June 21, 2013 /PRNewswire/ --DVI, a Dominion company that
offers technology to utilities to plan, manage and validate grid efficiency,
announced today that it has been selected by Modesto Irrigation District (MID)
to provide a number of advanced applications through the adoption of the
EDGE^® software suite. EDGE^® will be used in conjunction with the existing
Silver Spring Networks advanced metering infrastructure (AMI) deployment to
provide MID with advanced Conservation Voltage Reduction (CVR) and Volt/Var
Optimization (VVO) capabilities.

EDGE^® is a modular and adaptive conservation voltage management solution
enabling utilities to deploy incremental grid-side energy management that
requires no behavioral changes or purchases by end-use consumers. EDGE^®
provides significant and sustainable energy savings of as much as 4 percent
through integrated planning, execution and validation of grid side energy
efficiency management.

"DVI looks forward to working with MID to be a key part of its grid efficiency
strategy," said DVI Executive Director Todd Headlee. "MID, as with other
utilities in the California market, is actively seeking solutions to optimize
their distribution system for efficiency and reliability,both of which are
cornerstones of the EDGE^® grid optimization platform."

"MID has been looking at a number of advanced applications to leverage the
capabilities of our Silver Spring AMI deployment," said Tom Kimball, assistant
general manager for MID. "As we considered our CVR and VVO strategy, DVI's
patented approach of using AMI data for circuit optimization planning,
management and control, and measurement and verification was a clear
differentiator versus other solutions available on the market."

"High voltage levels on the grid lead to energy waste, higher energy bills,
and unnecessary carbon dioxide emissions. We are delighted to partner with DVI
to enable Modesto Irrigation District to deliver their customers a proven way
to increase energy efficiency without requiring changes in consumer behavior,"
said Anil Gadre, executive vice president of Products, Silver Spring Networks.
"Conservation Voltage Reduction is a proven technique to leverage existing
smart grid investments to lower voltage levels and save significant amounts of

Since 1994 MID has delivered on average 36 million gallons per day of treated
drinking water to the City of Modesto, about one-half of its annual needs. A
five-member elected Board of Directors governs MID and sets water and electric
rates. MID operates on a not-for-profit basis. Our goal is to provide reliable
service at the lowest possible cost. For more information visit www.mid.org.
